forces involved in size reduction in a ball mill

Simulation Of Size Reduction In Ball Mills And Dem. The mill with 30 cm in diameter and 30 cm in length and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included.For such a small mill, one could also include the ore or powder charge.

Size reduction of material using ball mill - Labmonk

Aim: The aim of the experiment was to achieve size reduction of the given granular material using a ball mill. REQUIREMENTS. Apparatus: Ball mill. Sieve set. Weighing balance. Sample. PROCEDURE. Kept 100 gm of rice and charge it to series of sieves to get pregrinding size distribution. Continuous sieving for 10 minutes. Weigh the mass of rice retained on each sieve. Load the rice into ball mill along with metal
